Resolver Option MCB 103

MCB 103 Resolver option is used for interfacing
resolver motor feedback to FC 300 Automation-
Drive. Resolvers are used basically as motor feed-
back device for Permanent Magnet brushless
synchronous motors. When the Resolver option is
ordered separately the kit includes:
• Resolver option MCB 103
• Enlarged LCP fixture and enlarged termi-
nal cover
Selection of parameters: 17-5x resolver Inter-
face.
The resolver interface must support one resolver
with the following specifications:
